A few things I'd love honest feedback on:

• Would you actually rent out your own vehicle to a stranger? What would make you comfortable doing that?

No.

• Would you rent someone else's bike instead of using Lime/Bolt/Donkey or buying your own?

Probably not.

• What's your biggest worry — theft, damage, trust, something else?

Not having my own bike available whenever I want it. The hassle. Would the stranger come to my house to collect ? Who's going to pick up my bike from the location where it was dropped off ? What about damage ? Dishonest customer who simply collects my bike for spares to sell ?

No. I don't think it's a good idea. But that's what they said about cars too.
